9106 - Time of day recording apparatus and apparatus for measuring, recording or otherwise indicating intervals of time, with clock or watch movement or with synchronous motor (for example, time registers, time-recorders):

HTS Code 9106 encompasses apparatus designed for recording or measuring the passage of time, specifically focusing on time-of-day recording and interval measurement. These devices are characterized by their integration of a clock or watch movement, or by the use of a synchronous motor to drive their timekeeping functions. Examples include time registers, which log specific times of an event, and time recorders, commonly used for employee attendance tracking. The core function of these goods is to accurately capture and display temporal information, distinguishing them from general timekeeping devices that do not have a recording or interval-measuring purpose.

This category is situated within Chapter 91, which deals with clocks and watches. However, HTS 9106 specifically targets instruments that go beyond simple time display to actively record or measure time intervals. Unlike simpler clocks or watches that primarily indicate the current time, the apparatus in 9106 are functional tools for documenting when events occur or how long they last. Their inclusion within Section XVIII highlights their precision measurement and instrumentation aspects, differentiating them from purely decorative or basic functional timepieces.

The subcategories within HTS 9106 are designed to differentiate based on the specific application and complexity of the time recording apparatus. HTS 9106.10.00.00 specifically addresses "Time registers; time-recorders," covering the most common examples of devices used for logging discrete time events or attendance. The residual category, HTS 9106.90, is for "Other" time of day recording and interval measuring apparatus that do not fall under the specific definition of time registers or recorders, allowing for the classification of less common or more specialized instruments within this broad functional group.
